2 Chapter Two: Page 36 Resources are things that we get from the living and nonliving environment to meet the needs and wants of a population. Some resources are basic materials, such as air, water, and soil; some are produced from basic resources, such as food, fuel, and building materials; and some resources are nonmaterial, such as quiet places, beauty, security, and safety.

3 Chapter Two: Page 37 Material resources Need Nonmaterial resources Nonrenewable resources Renewable resource Want resources you can touch like gas, wood and food something you must have in order to stay alive like air, water and nutrients resources that you cannot touch like happiness, peace, feelings of safety resources that can take a long time to be made again (thousands of years); sometimes these resources cannot be made again at all a resource that can be made again like living organisms anything you feel like having that is not a need

4 Chapter Two: Page 38 What are some examples of material and nonmaterial resources? Material resources include all things that can be physically touched; nonmaterial resources, like our feelings, cannot be physically touched. What is the difference between a need and a want? A need is something that is necessary for us to survive. A want is anything you feel like having that is not a need. Do you think material or nonmaterial resources are more important? They both are equally important. Our material resources allow us to stay alive while our nonmaterial resources keep us healthy, happy and willing to keep surviving. Are all nonrenewable resources unable to be made again? No. if the resource cannot be made for a very long time (we are talking thousands of years here!), it is still considered a nonrenewable resource.

Be certain to include everything you need to survive in your drawing. You may also add many of your wants in your drawing too! Label everything in your picture as either a need or a want. Answers will vary. The picture should contain both needs and wants.

6 Chapter Two: Page 40 Not all material resources are needed for every situation we are in. Our needs may, at times, compete with our wants. However, our needs must always be satisfied first before our wants.

7 Chapter Two: Page 41 Be careful what you ask for... Read the following story to your child: This summer, You are going to take a trip to an island that is very far away. It is going to take you three days to reach this island since it is far into the ocean. Once you get there, you will have all the resources you need. But your boat does not have anything on it at all right now. You need to start packing! The items listed below are the only things you will be able to take with you. How important are these things to keep you alive during your long trip? Write 1 by the most important thing you will need to take; write 2 by the second most important thing, and so on...until you reach 14. This one is the most useless thing you can use on your trip. Think carefully! Three days is a long time on a boat! Games Clothes Food Water TV Phone Coat Soap Candy Gasoline Umbrella Blanket Boat motor Matches

8 Chapter Two: Page 42 Here is my best attempt at placing these items in order. Feel free to alter them as needed. 1) Boat motor - Without a motor, you are not going to travel very far in your boat 2) Gasoline - How do you expect the boat motor to keep running? 3) Water - The ocean is filled with salty water so you will need fresh water to survive. 4) Food - You should be able to live for three days without any food. It would not be very much fun, though. So I would suggest carrying some with you. 5) Phone - This could come in handy if you need to contact someone for help. 6) Blanket - Even though you will be traveling during the summer, you still might get cold at night. 7) Clothes - Three days of wearing the same clothes? You are going to need to change your clothes. 8) Soap - Your body will not smell very good after three days without cleaning up. 9) Umbrella - If the weather is not very good, you may need this item to stay dry. 10) Coat - Remember, it is summertime. Your blanket should be all you need to stay warm. 11) Candy - I think you can go three days without sweets. 12) Games - Games may be helpful to pass the time, but you can live without them. 13) Matches - What are you planning on doing? Burning your boat? Keep these at home. 14) TV - Come on! Where are you going to plug it in?

9 Chapter Two: Page 43 Cycles exist in many different areas of life, especially with our renewable resources. However, some materials we use do not have a cycle. Identifying renewable from nonrenewable resources may help to take better care of the materials we use every day.

10 Cycles in life Children will explore several different cycles to identify renewable and nonrenewable resources. Chapter Two: Page 44 Materials: Paper and pencil Activity: Explain to child that cycles are an important aspect of life on earth. A cycle may go through many different steps, but it always arrives back at a same spot. Because of this, life can continue on our planet even though it may go through many changes. Show your child Cycle Scenario #1. There are many different stages between Baby and Adult, but it is a true cycle with new births from adults continuing the cycle of life. Ask the child if they can think of any endless cycles on their own. Examples may include: Day turns into night Night turns into day A seed is used to make a tree A tree makes new seeds Have the child draw a cycle of a typical day in their life.

11 Chapter Two: Page 45 Inform the child that once any step in a cycle is changed, the cycle does not exist anymore. Discuss what is wrong with the following process: Oil is taken from the ground Oil is used to make gasoline for our cars Our cars use up their gasoline We fill up the cars with more gasoline (This is not a true cycle, because it cannot go on forever oil is a nonrenewable resource.) Have the child read through the following list of scenarios and determine if each one is a true cycle or not. If it is not a true cycle, have them draw what needs to be done to make it into a true cycle. Cycle scenarios #1 Buy a car Drive a car Wreck a car Throw the car away Buy a new car #3 A seed grows in the ground A seedling is formed The seedling grows into a large plant The plants makes seeds The seeds fall to the ground #2 Water in the ocean heats up and turns to steam Steam cools and forms a cloud The cloud provides rain Rain fills up the ocean #4 A tree is cut down to make paper The paper is used to make newspapers The newspapers are read by a person The newspaper is thrown out

12 Chapter Two: Page 46 #5 Plastic is made by a company The plastic is molded into a soda bottle The bottle is filled with soda and was drank during your lunch The bottle is thrown away #6 Bricks are used to make a building The building gets used and torn down The bricks are broken up and thrown into the trash #7 A soda can is drank by a child The can is melted down The melted metal is used to make a new soda can #8 Fall ends and winter begins Winter ends and spring begins Spring ends and summer begins Summer ends and fall begins

13 Answers: #1 (not a true cycle) In order to become a cycle, the wrecked car would have to be recycled. Chapter Two: Page 47 #2 (true cycle) This is the water cycle in action. #3 (true cycle) This is the life cycle of a plant. #4 (not a true cycle) The newspaper would need to be recycled in some way to be a true cycle. #5 (not a true cycle) The plastic would need to be recycled in some way to be a true cycle. #6 (not a true cycle) The bricks would need to be recycled in some way to be a true cycle. #7 (true cycle) This is how a soda can is recycled. #8 (true cycle) This is how our seasons cycle throughout the year.
